CURRENT_MEETING_REPORT_
Reported by Jim Fullton/MCNC - CNIDR
Minutes of the Uniform Resource Identifiers Working Group (URI)
Session I
The meeting began with introductions, followed by Tim Berners-Lee's
presentation of the current URL draft. After discussion, the following
changes were proposed:
o Remove the AFS type.
o Add the ``mailto'' type, mailto:timbl@cern.ch, designed to be a
generalized mail transmission URL, and to help solve the problem of
how to contact an author.
o Wrapping---the formal URL wrapper is defined as <>.
A significant portion of the first session was spent discussing the
merits of creating a more generalized URL specification, with the
current specification as a specific case. Peter Deutsch advocates the
creation of this far more generalized specification and will examine the
issue further before the next IETF. During these discussions, it became
clear that the allowable character set needed refining.
The three general proposals were:
1. No restrictions on character sets.
2. Significant restrictions on the character set; i.e. the current
document.
3. Looser restrictions on the character set, but stay with the current
proposal.
Further discussion of URL issues was put off until the third session.
Chris Weider closed out the first session with a tutorial on current URN
issues.
Session II
The second session was spent on URN issues. Karen Sollins made a
presentation describing a system under development at MIT.
After further discussion of URNs, the group agreed that several issues
1
needed to be resolved before URNs could be properly specified:
o Detection of duplicates
o Fragment specifiers
o Version specifiers
o Type specifiers
After vast amounts of discussion, fragment, version, and typing
information was moved to a Uniform Resource Citation object, which has
not received a formal name. The URN was defined as a URN identifier
(RURNS), a naming authority string and an opaque string defined by the
naming authority as being unique within its name space. The whole URN
is wrapped in <>, just like a URL:
<URN:NA:OpStr>
A URN should occupy the same character space as a URL, for ease of
applications upgrades.
Session III
The discussion of URLs was continued in the third session. Mitra led a
discussion about modifications to the URL character set, and the group
agreed to modify the URL draft to allow the use of the following
characters:
:
;
=
'
''
Other characters not included in the draft are excluded.
A vote on the modified draft was held, with the group recommending
adoption of the modified draft by a vote of twenty-nine to one.
The URN format as described in the second session was informally agreed
upon, which led into a discussion of naming authorities. It is assumed
that many naming authorities will exist, including authorities within an
organization whose existence will not be known outside the organization.

Next Time
At the next IETF, an agenda item will be specified for a ``sub-ID''
discussion to define the format of the naming authority string and
opaque string.
